Texas Window Tint Law: The Basics
Texas window tinting laws are governed by the Texas Transportation Code and enforced by the Texas Department of Public Safety (DPS). The key metric is Visible Light Transmission (VLT) — the percentage of visible light that passes through the film and glass combined. A lower VLT means a darker tint.
Understanding these rules before you tint is essential. Non-compliant tint can result in a Class C misdemeanor fine and a required fix-it ticket that forces you to remove or replace the film at your own expense. At G1 Window Tinting, every installation is measured and verified for legal compliance before your vehicle leaves our shop.
2026 VLT Requirements by Window
Windshield
Tinting is only permitted on the top 5 inches or above the AS-1 line (whichever comes first). This strip must not be reflective. No tint below the AS-1 line is allowed — even clear films with metallic coatings are prohibited in this zone.
Front Side Windows (Driver & Passenger)
Must allow more than 25% of light in (25%+ VLT). This means tint films installed here — combined with the factory glass — must transmit at least 25% of visible light. Most factory glass already absorbs 5–10%, so ensure your film's VLT accounts for that.
Rear Side Windows
Any darkness allowed — no VLT minimum. You can go 5% limo tint, 20%, 35%, or any level you prefer. This applies to both sedans and SUVs/trucks.
Rear Window
Any darkness allowed — with one exception. If the rear window is tinted darker than 25%, Texas law requires dual side mirrors on the vehicle. Most vehicles already have them, but confirm before tinting.
Reflectivity Rules
Texas also regulates how reflective your tint can be. Metallic or mirrored tints are subject to the following limits:
- Front side windows: Must not be more than 25% reflective
- Rear side windows: Must not be more than 25% reflective
Non-reflective ceramic and carbon films are the safest choice. They provide superior heat rejection without the reflective appearance that draws officer attention.
Medical Exemptions
Texas allows a medical exemption for individuals with conditions such as lupus, melanoma, or photosensitivity disorders that require maximum UV and light protection. If you qualify:
- Obtain a signed letter from a licensed physician on official letterhead
- The letter must specify the medical necessity for darker tint
- Keep the letter in your vehicle at all times when driving
- Present it to law enforcement if stopped for tint darkness
G1 Window Tinting is experienced with medical exemption installations. We'll help ensure your vehicle is tinted correctly and that you have documentation ready.
Enforcement & Penalties in Austin
Austin-area law enforcement — including APD, Travis County Sheriff, and DPS troopers — actively enforce tint laws during traffic stops and vehicle inspection checkpoints. Here's what to expect if you're cited:
Fix-It Ticket
Most first offenses result in a fix-it citation requiring you to bring your vehicle into compliance within a set timeframe and provide proof of correction.
Class C Misdemeanor Fine
Fines can range from $25 to $500 depending on the officer's discretion and how significantly you exceed the limits.
Annual Vehicle Inspection
Texas inspection stations check tint as part of the annual safety inspection. Non-compliant tint will cause your vehicle to fail inspection.
Removal Costs
If you purchased tint elsewhere and it fails inspection or you're cited, removal and re-tint costs fall on you. Get it right the first time.

Frequently Asked Questions
Does Texas have a tint sticker requirement?
Texas does not require a sticker or certificate on your window to indicate legal tint, unlike some states. However, keeping your installer's documentation is smart practice in case you're ever questioned.
My factory glass is already dark — can I still tint?
Yes, but the combined VLT of your factory glass and added film must still meet the 25% minimum on front side windows. Bring your vehicle in and we'll measure before recommending a film.
Can I use 20% tint on my front windows?
Not legally. Texas requires more than 25% VLT on front side windows. 20% film on factory glass typically results in a combined VLT well below 25%, making it non-compliant and subject to citation.
What happens if I fail the annual inspection for tint?
You'll receive a rejection sticker and will need to have the non-compliant tint removed or replaced before your vehicle can pass. The inspection station will note the specific windows that failed.
